Introduction
My topic was the Internet, especially the TCP/IP; the URL, the DNS and ISPs. To understand these concepts it is indispensible to know, what Computer Communication Protocol is. We can define it as a description of the rules computers must follow to communicate with each other.
TCP/IP
TCP/IP stands for Transmission Control Protocol / Internet Protocol. It is the communication protocol for communication between computers on the Internet or the way how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.
History
TCP/IP was initially designed to meet the data communication needs of the U.S. Department of Defence (DOD). In the late 1960s the Advanced Research Projects Agency (ARPA, now called DARPA) of the U.S. Department of Defence began a partnership with U.S. universities and the corporate research community to design open, standard protocols and build multi-vendor networks.
Structure
There are protocols for handling data communication inside the TCP/IP: * TCP (Transmission Control Protocol) communication between applications * UDP (User Datagram Protocol) simple communication between applications * IP (Internet Protocol) communication between computers * ICMP (Internet Control Message Protocol) for errors and statistics * DHCP (Dynamic Host Configuration Protocol) for dynamic addressing
TCP - is responsible for verifying the correct delivery of data from client to server. Data can be lost in the intermediate network. TCP adds support to detect errors or lost data and to trigger retransmission until the data is correctly and completely received.
